Seeds with the same segments as other seeds are deduplicated

Parameters

ctx	The event's context to access StoreGate & Conditions
segments	Full segment container

private

Attempts to fit the track seed candidate to a full track and returns whether the fit succeeded.

Parameters

gCtx	Geometry context to access the alignment of the surfaces
mCtxc	Magnetic field context to access the field map during the fit
cCtx	Calibration context to access the calibration constants from Store gate during the track state filling
seed	The seed of interest to fit
outContainer	Mutable track container to which the output track is written

Add the links to the segments making up this track as an extra column. Use the indices of the segment objects which can later be transformed into a full ElementLink as there is only one SegmentContainer from which the seeds are built

virtual std::vector< Gaudi::DataHandle * > AthCommonDataStore< AthCommonMsg< Gaudi::Algorithm > >::outputHandles ( ) const

Return this algorithm's output handles.

We override this to include handle instances from key arrays if they have not yet been declared. See comments on updateVHKA.

prepareFit()

std::pair< MsTrackFindingAlg::OptBoundPars_t, MsTrackFindingAlg::MeasVec_t > MuonR4::MsTrackFindingAlg::prepareFit ( const Acts::GeometryContext & tgContext, const Acts::MagneticFieldContext & mfContext, const Acts::CalibrationContext & calContext, const MsTrackSeed & seed ) const

private

Prepares the input by the fit by collecting the measurements on the segment &.

Parameters

gCtx	Geometry context to access the alignment of the surfaces
mCtxc	Magnetic field context to access the field map during the fit
cCtx	Calibration context to access the calibration constants from Store gate during the track state filling
seed	The seed of interest to fit

Fetch the measurements from the segment & find the first segment which has phi hits

Ensure that the drift signs from the fit are stamped onto the Uncalibrated measurements

The middle or outer segment provide the phi information. Not so easy becasue we want to Take the y0 & precision direction from the inner segment but the phi & x0 from a straight line extrapolation onto the plane

Extrapolate the seed segment onto the inner plane. We want to take the precision intercept from the inner segment and the non-precision intercept from the extrapolated segment

the tube form the back extrapolated segment

The extrapolation needs to go backwards and stay within the surface boundaries
